Screws are passed through the screw holes on the flanges and locked with the screw hole columns to achieve a stable connection between the two.

[0059] The working principle of the entire integrated waterway board is as follows: the municipal tap water filtered through the filter element enters the pure water inlet pipe of the zero-stale water waterway board from the pure water outlet of the main waterway board. If drainage is required, it directly enters the drainage solenoid valve, and enters the drainage inlet of the detachable main waterway board from the drainage outlet of the drainage solenoid valve through the drainage outlet pipe of the detachable zero-stale water waterway board, and finally is discharged from the waste water outlet of the detachable main waterway board;

[0060] If return water is required, it will directly enter the return water solenoid valve, and enter the return water inlet of the main water circuit board through the return water outlet 7 of the zero-stagnation water circuit board from the return water outlet of the return water solenoid valve, and then flow back to the filter element for re-filtration.

[0061] In this embodiment, if Figure 10-12 As shown, the door assembly 3 includes a panel 31 and a door cover 32. The panel 31 is provided with a through hole 311 intersecting the central through frame 5. The filter element 8 is inserted into the inner cavity of the central through frame 5 through the through hole 311 and connected to the waterway on the main waterway plate 62.

[0067] It should be noted that the female buckle 312 and the panel 31 are an integrally formed structure or a split structure; if a split structure is adopted, it can be fixed to the panel 31 by means of screws, buckles, etc.;

[0068] like Figure 13-14 As shown, when the filter element needs to be installed, insert the filter element into the inner cavity of the middle-through frame, push the filter element inward, and stop moving when the push rod mating part on the filter element contacts the push rod. At this time, turn the door cover upward, and the door cover pushes the filter element into the middle-through frame until the male buckle contacts the female buckle, and the male buckle moves inward and locks with the female buckle. The door cover reaches the locked state, and the filter element installation is completed. At this time, the filter element is connected to the waterway, and the water purifier can work normally.

[0069] When the filter element needs to be removed, press the male buckle and the male buckle will be separated from the female buckle. At this time, turn the door cover downward, the push rod mating part on the filter element contacts the push rod, and continuously pull the filter element outward until the filter element is disengaged from the waterway plate.

The electric control board 14 recognizes, according to a set program, that the electronic anti-counterfeiting label on the filter element 8 corresponds to the electronic anti-counterfeiting board on the middle frame. Only then can the machine operate normally. If it is recognized that there is no electronic anti-counterfeiting label on the filter element 8, the electric control board 14 will issue an alarm command and the machine will not be able to operate normally.

[0073] In this embodiment, a control display panel is also provided on the panel 31, and a filter element life display button, a zero stale water and non-zero stale water switching button, and a WIFI network configuration button are provided on the control display panel, which is convenient and intelligent.

[0075] To sum up, through the above design, the shell of the water purifier is a sleeve integral structure, which does not need to be disassembled, reducing the mold cost and the production and assembly cost. There will be no problems such as uneven assembly gap and step difference in appearance. In addition, the adapter is placed inside the machine, and a water-proof baffle is set to separate water and electricity, making the appearance more simple and beautiful; the whole machine is compactly arranged, small in size, and simple in structure. The filter element can be taken out simultaneously when the door is opened, and the filter element can be replaced more conveniently and quickly; the filter element anti-counterfeiting alarm function makes drinking water safer and more reliable, and the switching mode between zero stale water and non-zero stale water (water-saving mode) can be controlled by one button on the panel, which is easy to operate.
